设alpha_(1), alpha_(2), alpha_(3)是三元非齐线性方程组Ax = b的三个互不相同的解，且R

设$\alpha_{1}, \alpha_{2}, \alpha_{3}$是三元非齐线性方程组$Ax = b$的三个互不相同的解，且$R

  • A. = 2$，$\alpha_{1} = (1, 2, -1)^T$，$\alpha_{2} + \alpha_{3} = (0, 1, 3)^T$，则$Ax = b$的通解是()。
  • A. $k(2, 3, -5)^T + (1, 2, -1)^T$
  • B. $k(1, 2, -1)^T + (2, 3, -5)^T$
  • C. $k_{1}(0, 1, 3)^T + k_{2}(1, 2, -1)^T$
  • D. $k(2, 3, -5)^T + (0, 1, 3)^T$
